COUNT[31:0]
Integration Count Value
The COUNT field holds the count of filtered outputs integrated. The control of the integration sum
and update of this register is determined by the register DECFILTER_MXCR (see
Section 26.4.2.3, Decimation Filter Module Extended Configuration Register
(DECFILTER_MXCR)
”). The register is updated together with DECFILTER_FINTVAL, only upon
an integration output request.

SUM_VALUE
[31:0]
Integration Sum Value. The SUM_VALUE[31:0] field holds an unsigned number representing the
sum of filtered output values, continuously updated as the integration proceeds. The control of
the integration sum is determined by the register DECFILTER_MXCR (see
Section 26.4.2.3,
Decimation Filter Module Extended Configuration Register (DECFILTER_MXCR) ”).
